Hi All
I've just fixed the issue with the site, sorry it wasn't sooner I wasn't aware of the issue until now. For some reason the server backup had decided to retain multiple backups and filled up the disk so things like the DB server were unable to run.
For anyone emailing me to say the site wasn't working thanks but please include the site name as we host a lot
I'll keep a close eye on it over the next few days to make sure this doesn't happen again.
Thanks
Ash
